Mitanni (Hittite cuneiform KUR URUMi-ta-an-ni, also Mittani Mi-it-ta-ni) or Hanigalbat (Assyrian Hanigalbat, Khanigalbat cuneiform Ḫa-ni-gal-bat) was an Hurrian-speaking state in northern Syria and south-east Anatolia from ca. 1500 BC–1300 BC. Founded by an Indo-Aryan ruling class governing a predominately Hurrian population, Mitanni came to be a regional power after the Hittite destruction of Amorite Babylon, and a series of ineffectual Assyrian kings created a power vacuum in Mesopotamia. At the beginning of its history, Mitanni's major rival was Egypt under the Thutmosids. However, with the ascent of the Hittite empire, Mitanni and Egypt made an alliance to protect their mutual interests from the threat of Hittite domination. At the height of its power, during the 14th century BC, it had outposts centered around its capital, Washukanni, whose location has been determined by archaeologists to be on the headwaters of the Khabur River. Eventually, Mitanni succumbed to Hittite and later Assyrian attacks, and was reduced to the status of a province of the Middle Assyrian Empire.

Their sphere of influence is shown in Hurrian place names, personal names and the spread through Syria and the Levant of a distinct pottery type.
